SEED CLEANER. AND SEPARTOR.

Laiaioi.

To all whom t may concern:

Be it known that I, WILLIAM F. HART- RAMPF, a citizen of the UnitedStates, residing at Forest Grove, in the county of Washington and Stateof Oregon, have invented certain new and useful Improvements in SeedCleaners and Separators; and I do declare the following to be a full,clear, and exact description of the invention, suchv as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to improvements in machines for cleaning seed andseparating it from chaff and the like with which it is mixed, the objectbeing to provide a comparatively simple and inexpensive machine whichregardless of these advantageous characteristics will be highlyeliicient and durable.

lVith this general object in view, the invention resides in certainnovel features of construction and in unique combinations of parts to behereinafter fully described and claimed, the descriptive matteil beingsupplemented by the accompanying drawings which constitute a part ofthis application and in which:

Figure 1 is a front elevation of a machine constructed in accordancewith my invention; Figs. 2 and 3 are end elevations; Fig. '-1 is acentral transverse sectional view taken on the Fig. 5 is a perspectiveview of the roller car rying bars to be describedfand the adjustingmeans for one of said bars.

ln specifically describing the construction shown in the drawings abovebriefly described, similar characters will be placed on correspondingparts throughout the several views and reference will be herein made tothe numerous elements by their respective indices. To this end, thenumeral 1 designates the frame of the improved machine, which frameincludes a pair o-f spaced rear standards 2 standing substantiallyupright but inclined to some extent toward one end of the machine.Similarly positioned front standards 3 are spaced in advance of thestandards 2 and rigidly held by transverse bars 1. The standards 2 and 3at one end of the machine are pivoted by bolts or the like 5 to feet 6which are adapted to rest on the floor of a barn or the like while thestandards at the other end of the machine are equipped with l.shapedbrackets 7 through whose horizontal portions upright plane of the line 41 ofFig.y 1; and,

jack screws 8 are threaded, the lower ends of said screws preferablyrestingin metallic socket members 9 which will -bear on the aforesaidfloor.

Rear vertically disposed bars 10 are secured by bolts or the like 11 -tothe front sides of the standards 2 while front upright bars 12 aremounted for vertical shifting adjacent the front sides ofthe `standards3, said bars 12 preferably havingslots 13 receiving lag screws or thelike 14 which guide them in their vertical movement. A rear series ofslightly inclined rollers 15 extend between and are rotatably supportedby the rear bars 10 while similarly positioned rollers 16 are supportedby the front bars 12, said rollers 16 beingl disposedinplanes above therollers 15 asfshown, the distance between such planes being controlledby the vertical adjustment of the bars 12 in the manner to be described.V

Upper and lower parallel transverse links 17 and 18 are pivoted to thebars 10 and 12, the upper links being extended `forwardly beyond saidbars 12 and being shown in the present embodiment of the inventionasprovided with L-shaped brackets `20 pivoted thereto and carrying nuts21, jack screws 22 being threaded through said nuts. The screws 22 aresupported rotatably by angle iron brackets 23 which depend `from thefront ends of rigid transverse bars 24, the latter being secured to thefront and rear standards of the frame 1 and preferably incliningupwardly and forwardly. rlhe brackets 23 rotatably support alongitudinally disposed shaft 25 upon which bevel gears 26 are secured,said gears meshing with similar gears 27 secured to the upper ends ofthe screws 22 whereby rotation of the shaft 25 bv means of a hand wheelor the like 28 will simultaneously adjust both links 17 vertically, theresult being that the bar 12 will be similarly moved.

An endless belt 29 of canvas or other suitable material is trainedaround the rollers 15 and 16 and around other rollers 30 adjacent therear of the frame 1, said belt thus having a plurality of upwardly andforwardly inclined reaches 31 upon which the chaff and seed to beseparated are deposited by means of tubes 32 depending from a suitablehopper 33. Sprocket wheels 34 are secured to one end of the rollers 30and to the upper. and lower rollers 16, a sprocket chain '35 beingtrained around-said wheels ido whereby they will all be rotated inunison to drive the belt 29 when power is applied to the machine by apulley 36 on the shaft of the roller 30 or by any other preferred means.The bearings of the uppermost roller 30, which bearings are designatedat 37, are mounted for vertical movement and may be adjusted by theprovision of screws or the like 38. The function of this arrangement isthat the belt 29 and chain 35 may be tightened when necessary.

- Preferably used in conjunction with the parts above described is abrush 39 which is mounted in rear of the frame 1 and engages the belt 29to clean the latter of all chaff and the like which may have adheredthereto.

In use, the hand wheel 28 will be rotated to adjust the front bars 12vertically to the proper extent for giving the necessary transverseinclination to the reaches 31 of the belt 29 and the jack screws 8 willalso be turned to impart the required longitudinal inclination to saidreaches. These adjustments having been made, the machine will be drivenand the chaff and seed to be separated will be fed into the hopper 33from which it travels onto the reaches 31 at the lower ends of thelatter. These reaches will now convey all chaif and the like upwardlyand discharge it at the front side of the machine but the seed willremain adjacent the rollers 15 and will travel along the belt to thedischarge end of the machine, suitable chutes 40 being preferablyprovided for guiding the discharged seed into sacks, measures or othersuitable receptacles. The

Vmembers 40 are merely shown for illustrative purposes and it is to beunderstood that any desired means may be employed for receiving thecleaned seed from the machine.

From the foregoing, taken in connection with the accompanying drawings,it will be l obvious that although the machine is com- Copies o! thispatent may be obtained for paratively simple and inexpensive, it will beeiiicient and durable. Particular emphasis is laid upon the mounting andmanner of adjusting the rollers 15 and 16 in view of the extremesimplicity of this arrangement. The mounting of the entire frame 1constitutes another rather important feature of the invention.

In the foregoing, a number of specific details have been shown anddescribed for accomplishing probably the best results and in theaccompanying drawings such details have been illustrated, but it is tobe understood that within the scope of the invention as claimed,numerous changes may be made without sacrificing the main advantagesthereof.

I claim A seed cleaning machine comprising a frame including a pair ofvertically movable upright bars, vertically spaced rollers whose endsare supported by said bars, and a seed handling belt having portionstrained around the rollers; upper and lower parallel links at each endof the frame pivoted at their rear ends to said frame and pivoted at ornear their front ends to said vertically movable bars, the upper linksbeing extended forwardly beyond said bars, rigid arms projectingforwardly from the frame above said upper links, a longitudinallydisposed shaft carried by said arms, and means operable from said shaftfor raising and lowering the upper links in unison, said means beingconnected with the projecting front ends of said links.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
